Box Step-ups with Dumbbells for Calves, Butt and Thighs

If you've been to an aerobics step class you will be familiar with the low platforms that are used in the general step workouts.

But you can go harder with what's sometimes called a "box", which is a higher platform or step. Many gyms have them available.

And you can go harder still by doing what is called "marches" on the box platform. This "bouncing" exercise is in the category of plyometics. Done with weights it's a real butt and thigh killer -- but tough on the joints and tendons as well.

For now though, you might want to start with box steps, progress to dumbbell box steps and then see how you're going.
